Paradoxical role of new endosymbiotic associations: they facilitate the emergence of new partnerships, but inhibit deeper integration between hosts and guests (by favoring uncoordinated reproduction over synchronized ones). That is, easy come, easy go. #Endosymbiosis doi.org/10.1101/2025...

Currency exchange in endosymbiosis: early on, hosts’ investments generate a fortune in guest growth; near full reproductive synchronization, that same investment buys much less. That is, cheap early gains, expensive late ones.

Participants of the “Theory of Microbial Symbiosis” workshop standing together on the shore at the Hawaiʻi Institute of Marine Biology, with the ocean and trees in the background

Two researchers discussing their results shown on a screen

A group of four researchers gathered around a blackboard with equations. One is pointing at the board, another is writing on it, a third is taking notes on paper, and the fourth is observing the discussion

A wooden building situated on the shore, with palm trees in the background. A group of people is gathered in front of the building, engaged in conversation

This work stems from the “Theory of Microbial Symbiosis” workshop held last year at HIMB (Hawaiʻi Institute of Marine Biology), supported by the Gordon and Betty Moore Foundation @moorefound.bsky.social. Grateful to Joan Roughgarden and Lisa McManus for organizing such a fantastic workshop!

Great team work with Maria Martignoni, Lisa McManus, Taom Sakal, Armun Liaghat @armunliaghat.bsky.social ,
Bethany Stevens, Kyle Dahlin, Lucas Souza @lucasgenoma.bsky.social, Zoe Cardon, Cynthia Silveira, Seth Bordenstein @symbionticism.bsky.social, and Joan Roughgarden.

The top of the image shows a coral reef with a zoomed-in section highlighting the coral holobiont (comprising coral cells, bacteria, phages, fungi, and zooxanthellae). Below each component is its genetic material, collectively forming the "hologenome." At the bottom, a wasp is shown as another example of a holobiont. On the left, the wasp hosts symbionts such as bacteria and phages. In the center, two wasps share some symbionts with each other and the environment. On the right, a wasp lineage undergoes speciation, resulting in two wasp species, each with a distinct symbiont composition.

We discuss the limits of current theoretical host-microbe models and outline 3 key areas for future work:

1) Modelling the nested structure of holobionts
2) Capturing microbial transmission dynamics in #holobiont populations
3) Understanding symbiont-driven host evolution and speciation

Theory of host-microbe symbioses: Challenges and opportunities Growing insight into microbial symbioses highlights the need to model these systems mathematically. We discuss three areas requiring theoretical advan…

Our article on the challenges and opportunities in studying host-microbe symbioses is now published in Cell Host & Microbe! @cp-cellhostmicrobe.bsky.social

Introducing carbon assimilation in yeasts using photosynthetic directed endosymbiosis

Impaired photoacclimation in a kleptoplastidic dinoflagellate reveals physiological limits of early stages of endosymbiosis Dinophysis dinoflagellates use plastids stolen from prey. Garric et al. show that these plastids cannot synthesize a complete phycoerythrin, a crucial photosynthetic protein. Dinophysis thus relies on prey ingestion for photoacclimation. It is noteworthy that some Dinophysis have acquired phycoerythrin synthesis genes from cryptophytes during evolution.

'The organelle is the fourth example in history of primary endosymbiosis—the process by which a prokaryotic cell is engulfed by a eukaryotic cell and evolves beyond symbiosis into an organelle.'
